Maximum-to-minimum difference
Compute the maximum-to-minimum difference of the input data x.
peak2peak(x, MARGIN = 2)
x |
the data, expected to be a vector, a matrix, an array. |
MARGIN |
a vector giving the subscripts which the function will be
applied over. E.g., for a matrix 1 indicates rows, 2 indicates columns,
c(1, 2) indicates rows and columns. Where |
The input x can be a vector, a matrix or an array. If the input is a
vector, a single value is returned representing the maximum-to-minimum
difference of the vector. If the input is a matrix or an array, a vector or
an array of values is returned representing the maximum-to-minimum
differences of the dimensions of x indicated by the MARGIN
argument.
Support for complex valued input is provided. In this case, the function
peak2peak identifies the maximum and minimum in complex magnitude, and
then subtracts the complex number with the minimum modulus from the complex
number with the maximum modulus.
Vector or array of values containing the maximum-to-minimum
differences of the specified MARGIN of x.
